ADOLPH E. AESGHLIMANN, OF TAYLOR, TEXAS, ASSIGNOR OF ONE-THIRD TO M. F. KLATTEN- HOFF AND ONE-THIRD TO JOHN F. SOHRIEVER, BOTH OF TAYLOR, TEXAS.

WRENCH.

To all whom it may concern:

Be it known that I, ADoLPrr E. Ansonnr- MANN, a citizen of the United States, residing at Taylor, in the county of l/Villiamson and State of Texas, have invented certain new and useful Improvements in Wrenches; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in wrenches and has relation more particularly to that class of wrenches known as sliding adjustment.

It is an object of the invention to provide a novel device of this character which can be readily employed either as a nut wrench or a pipe wrench.

It is also an object of the invention to pro vide a novel device of this character comprising a hollow stationary member and a movable member projecting therein, said movable member having a movement laterally of the hollow member to increase the gripping action of the jaws carried by both of the members when strain is made on the members in one direction.

It is also an object of the invention to provide a novel device of this character consisting of a hollow stationary member and a movable member projecting within said hollow member, the hollow member having rotatably mounted thereon an adjusting member engaging an end of the movable member.

It is also an object of the invention to provide a novel device of this character which will be simple in construction, efficient and advantageous in practice and comparatively inexpensive to manufacture.

With the above and other objects in view, the invention consists of the details of construction and in the novel arrangement and 45 combination of parts to be hereinafter more particularly referred to.

In describing the invention in detail, reference will be had to the accompanying drawings forming part of this specification wherein like characters of reference denote corresponding parts in the several views and in which,

Figure 1 is a view in side elevation of the invention, and, Fig. 2 is a view partly in Specification of Letters Patent.

section and partly in elevation illustrating the various details of the invention.

In the drawings, 1 denotes the stationary member formed of any desired material terminating at one end in the jaw 2. This member 1 is hollow and has its front edge inclined downwardly from the jaw 2 to its opposite end as is fully shown in Fig. 2. The end of the member 1 opposed to the jaw 2 is provided with the approximately rightangular flange 4: which is adapted to project within a runway 5 in a knob 6. T iis runway may be formed in any desired man ner but it has been found best in practice that initially the knob be provided with an upstanding annular flange which when applied to the member 1 is upset about the flange 4. This knob is free to rotate around the member 1 and is provided with a projected portion or shank 7 extending within the lower portion of the member 1. The knob and its shank 7 is provided with a longitudinally disposed recess 8. The upper portion of the recess 8 is reduced in diameter and screw-threaded as at 9. This threaded portion of the recess is engaged by the threaded lower end 10 of the movable member 11 which is formed of a solid piece of material and projects within the hollow member 1 and is of less width than the hollow member 1. The upper end of the movable member 11 terminates in the jaw 12 arranged above the jaw 2 hereinbefore referred to.

It is thought to be apparent when it is desired to adjust the jaw 12 with relation to the jaw 2, it is only necessary to rotate the knob 6 in the desired direction. Normally the member 11 is held in contact with the straight rear wall of the member 1 by a fiat spring 13 which has one end secured to the inclined portion of the jaw 2 and its opposite end bearing against the member 11.

It is thought to be apparent that when the jaws 2 and 12 are caused to contact with an article, more especially a pipe and a forward pull is given to the stationary member 1, the inclined face 3 of the stationary member 1 will permit sufficient movement of the stationary member 1 independent of the member 11 as to greatly enhance the gripping of the jaws 2 and 12. It might also be well to state further that the opposed faces of the jaws 2 and 12 are toothed or serrated.

I claim: 1

In a device of the character described, the combination of a hollow stationary member having a jaw at one end and a flange adj acent its opposite end, said hollow member having one face inclined longitudinally from its jaw to the opposite end, a knob having an angular runway in which the flange projects, a shank formed with the knob projecting within the stationary member, said shank and knob being provided with a longitudinal recess, an upper portion of the recess being reduced in diameter, said reduced portion of the recess being threaded, a movable member projecting within the hollow stationary member, the inner end portion of the said movable member being in threaded engagement with the threaded portion of the recess of the shank and knob, said movable member having a jaw acting in conjunction with the jaw of the stationary member and a spring interposed between a wall of the hollow stationary member and a wall of the movable member.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
